Title: Improved superconductors and method for the preparation thereof
IPC: C23C10/22
Filed: 1961-11-23
Abstract: A superconductor is made by reacting a solid superconductive base member, such as Nb wire or V strip, with an element, or alloy of elements, having a different number of valency electrons, e.g. Sn or Ga as vapour or fused bath, Si vapour, Ga or Al powder, preferably in an inert atmosphere, e.g. A or under vacuum at a temperature below the melting point of the member, to cause the element to diffuse into the member converting at least a portion thereof to an integral, continuous layer of a crystalline reaction product, e.g. Nb3Sn, V3Ga, Nb3Al, SiV3, GaNb3, GeNb3, BeV3, InNb3, SnTa or SnV3, having a b -tungsten structure and superconductive properties superior (higher critical temperature) to either the base member or element.  For example, niobium wire may be reacted by (a) diffusing tin vapour into it at 1200  DEG C. in an evacuated chamber, (b) heating it at 1350 DEG C. with powdered aluminium, or (c) immersing it in a fused tin bath containing inert diluents such as Cu or Ag prior to heating the coated wire to 1200  DEG C. in A atmosphere.  The diffusion reaction may be conducted by decomposing volatile compounds of the element such as carbonyls or halides.

Abstract: 1361783 Synchronizing systems MARCONI INSTRUMENTS Ltd 11 July 1972 [10 Sept 1971] 42265/71 Heading H3A A frequency synchronizer comprises a resettable divider 6 for dividing an input frequency signal from 2 by a selected factor, i.e. determined by setting of stores 23-26, a phase or frequency comparator 7 for comparing the output of the resettable divider with a reference frequency signal derived from generator 10, 9, an indicator 12 for indicating when the frequencies compared are not in a predetermined ratio, and a timing circuit 11 for resetting the divider 6 when a predetermined time lapses without a signal being produced at the output of the divider 6. The divider 6 output is further divided by the ratio which it should bear to the frequency of the reference signal provided by the divider 9 and compared in frequency at 8 with the reference signal. If the compared frequencies are unequal, a signal is applied via OR gate 18 for resetting the divider 6. Thus the output of the comparator 7 applied to the indicator 12 is a fluctuating signal instead of a steady D.C. voltage and an operator can easily rectify any wrong initial settings.

Abstract: 952,577. Capacitors. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 8, 1962 [Nov. 10, 1961], No. 42314/62. Drawings to Specification. Heading H1M. An oxide film solid electrolyte capacitor is produced by anodizing a sintered porous electrode body of aluminium, tantalum, or other film-forming metal having a connecting lead, positioning an auxiliary electrode of tantalum or other incorrodible metal closely adjacent to the electrode without contact, and coating the electrode with a layer of a salt, e.g. manganous nitrate, which is pyrolytically convertible into a semi-conductor layer, e.g. manganese dioxide. The auxiliary electrode is in contact with the salt layer, and during pyrolysis a voltage of the order of the working voltage of the finished capacitor is connected between the porous electrode and the auxiliary electrode with the same polarity as the anodizing voltage. Subsequently a graphite and then a metallized coating for attachment of a connecting lead are applied over the semi-conductor layer. The auxiliary voltage may be applied during the whole or part of the pyrolysis and also during the application of the graphite layer, and the capacitor electrode may be of wire or foil instead of a sintered body.

Title: Process for the manufacture of polymers or copolymers of olefinically unsaturated organic compounds
IPC: C08F4/28

Abstract: Polymers or copolymers of olefinically unsaturated organic compounds are manufactured in aqueous dispersion with the use of a redox system comprising an inorganic or organic per-compound and as reducing agent hydrogen and/or a compound that splits off hydrogen, the reaction being carried out in the presence of a colloidally dispersed noble metal of Group VIII (i.e. Pt, Pd, Rh, Ru, Os and Ir).  Any olefinically unsaturated compound capable of polymerizing alone or in admixture with one another with the use of a free radical-forming agent can be used, e.g. olefines; vinyl or vinylidene halides; vinyl esters; acrylic compounds; unsaturated mono- or di-carboxylic acids or anhydrides thereof or mono- or di-esters of these acids; unsaturated aldehydes; allyl esters; N-vinyl-compounds; vinyl sulphonic acids or salts thereof and dienes.  Inorganic or organic per-compounds customarily employed in redox systems are used, the amount preferably being from 0.001 to 2% by weight of per-compound calculated on the monomer or monomers used. Reducing agents mentioned are sodium, lithium, calcium, boron and aluminium hydrides, lithium borohydride, sodium borohydride, and lithium-aluminium hydride. The partial pressure of the hydrogen used as reducing agent is preferably within the range 0.01 to 100 atmospheres absolute. The noble metals are preferably used in the form of aqueous sols which may be stabilized by adding protective colloids.  The proportion of noble metal is preferably 0.000001 to 0.1% by weight calculated on the weight of monomers used.  The ratio by weight of water to monomer may be within the range 1:2 to 10:1.  As dispersing agents there may be used any emulsifying agents or protective colloids normally used in the polymerization of unsaturated organic compounds in aqueous dispersion; they may be used singly or as mixtures, the amount used being in the range 0.1 to 2% by weight of the monomers.
